“…The data supplied in Table 2 and PCA analysis suggest the major oxygenated sesquiterpenes caryophyllene and its derivatives, as well as hexahydrofarnesyl acetone, can be potent phytotoxic agents. The phytotoxic EOs derived from Baccharis patens [ 29 , 30 ], Heliotropium curassavicum [ 7 ], Cullen plicata [ 50 ], Scutellaria strigillosa [ 51 ], Acroptilon repens [ 52 ], Lantana camara [ 23 ], Teucrium arduini , Teucrium maghrebinum , Teucrium polium , Teucrium montbretii [ 31 ], and Ailanthus altissima [ 53 ] were reported to have all or one of β -caryophyllene, (-)-caryophyllene, and caryophyllene oxide as primary compounds. These reports indicate a strong correlation between the phytotoxic activities of EOs and the presence of these compounds as main components.…”

Herbicides are natural or synthetic chemicals used to control unwanted plants (weeds). To avoid the harmful effects of synthetic herbicides, considerable effort has been devoted to finding alternative products derived from natural sources. Essential oils (EOs) from aromatic plants are auspicious source of bioherbicides. This review discusses phytotoxic EOs and their chemical compositions as reported from 1972 to 2020. Using chemometric analysis, we attempt to build a structure-activity relationship between phytotoxicity and EO chemical composition. Data analysis reveals that oxygenated terpenes, and mono- and sesquiterpenes, in particular, play principal roles in the phytotoxicity of EOs. Pinene, 1,8 cineole, linalool, and carvacrol are the most effective monoterpenes, with significant phytotoxicity evident in the EOs of many plants. Caryophyllene and its derivatives, including germacrene, spathulenol, and hexahydrofarnesyl acetone, are the most effective sesquiterpenes. EOs rich in iridoids (non-terpene compounds) also exhibit allelopathic activity. Further studies are recommended to evaluate the phytotoxic activity of these compounds in pure forms, determine their activity in the field, evaluate their safety, and assess their modes of action.

“…This may occur because some compounds do not have hydrogen atoms in the allylic and / or benzyl positions. Previous studies conducted on Baccharis species which produced β-pinene as major compound or in high contents showed low free radical capture by DPPH [57,58]. Therefore, such compound is probably not the main responsible for the antioxidant activity of the essential oils of various plant species.…”

Baccharis dracunculifolia DC. is a Brazilian native plant, presenting wide chemical diversity and numerous pharmaceutical and industrial applications. This research assessed the yield, antioxidant activity and the chemical similarity of essential oils from 10 populations of B. dracunculifolia in the state of Paraná, southern Brazil. The extraction of the volatile compounds was carried out by hydrodistillation, the chemical composition was determined by GC/FID and GC/MS and the antioxidant activity by the DPPH method. The essential oil yield of wild B. dracunculifolia populations ranged from 0.14 to 0.87%. The oils were predominantly composed of oxygenated sesquiterpenes (34.16 -51.01%), monoterpene hydrocarbons (18.02 -46.17%) and sesquiterpenes hydrocarbons (9.60 -17.70%). The major compounds found in all populations were β-pinene (7.65 -29.8%) and (E)-nerolidol (9.11 -21.68%). Essential oil solutions (20%) from different populations presented antioxidant capacity ranging from 27.78 to 91.67%. A negative correlation was found between the antioxidant activity and spathulenol (r = -0.696). Multivariate analyses HIGHLIGHTS  Essential oils from populations of B. dracunculifolia were investigated.  β-pinene and (E)-nerolidol were the main compounds in B. dracunculifolia populations.  The difference in the chemical profile of the essential oils is quantitative only. There is a negative correlation between the antioxidant activity and spathulenol.Tomazzoli, M.M.; et al.
